Transient by using staedy result
 

dear guys,

I am simulating a compressor,3D via Fluent 15.
I got a convergence in steady mode by using Moving references in impeller zone.
(impeller zone consists of blade,hub and Non rotating shroud)
Now I wanna get transient by using this results, I change reference frame to moving mesh, but residuals are diverged after 400-450 iteration.
I tried with too small time step(1e-6) and 40-50 iteration per step.
Also currant number is set to 0.01 -0.1, but it does not affect.

Any suggestion ?!
